Actually got your catalog inquiry and wanted to follow up on the Tirzepatide powder — we've been stocking this one pretty consistently lately, so lead time is usually about 5 business days if you need it faster our company can ship partial from our cold storage, but the full MOQ of 500mg or so might need a heads-up if you're ordering bulk, anyway the freight timeline is roughly 10-14 days with the dry ice packs depending on your location.

What it does is combine both GLP-1 and GIP agonism in a single molecule at over 99% purity per HPLC — we test each batch and the COA usually shows 99.2% or thereabouts, and handling the white powder at -20°C protected from light is pretty critical because even a few hours at room temp can degrade it noticeably, which some new buyers don't always realize until they get a less soluble batch.

For in vivo work that's where most researchers push this — the dual action on glucose metabolism and weight regulation is what's driving the interest, but this is absolutely not suited for anything beyond lab use since the PK profile in humans would be completely different from what you see in rodent models, and the molecular weight at roughly 4814 g/mol means reconstitution buffer choice matters more than people think.
Storage is the biggest headache actually — that -20°C requirement with light protection isn't just a suggestion, we've had returns form labs that left it out for a day and the powder clumped up or lost solubility, so I'd recommend aliquoting immediately upon receipt into individual vials since repeated freeze-thaw will kill the activity pretty fast.

We usually have stock but confirm lead time on orders over 5 grams because those require a separate production run and cold chain packging adds about 3-4 days — teh 5L drum is easier to handle for larger quantities but your reconstitution vehicle matters, and our last batch tested at 99.3% by HPLC with no detectable degradation peaks.
For a 10-gram order, lead time is typically 3-5 business days after payment confirmation. Larger quantities may take a bit longer depending on stock levels at our warehouse.
Yes, we include a COA with every batch, showing ≥99% purity and confirming the identity by HPLC and mass spec. Just request it when you place your order.
We can do custom packaging for research use, including smaller vials. Minimum order quantities may apply for custom sizes—let us know your needs and we’ll work it out.
Store it at -20°C in a freezer, protected from light. Keep it in its original airtight container to avoid moisture. Properly stored, it stays stable for at least 12 months.
Yes, every batch is tested by mass spectrometry to verify the molecular weight of 4813.527 g/mol, matching the formula C225H348N48O68. That data is included in the COA.
